Before running tests, you'll need to install the [web-push testing service](https://www.npmjs.com/package/web-push-testing-service):
8+
9+
```bash
10+
npm install web-push-testing-service -g
11+
```
12+
13+
NOTE: You might need to make sure command `web-push-testing-service` runs OK on cli. In my case on OSX, I needed to add a bash alias after install:
